COSTI E BENEFICI DELL’IMMIGRAZIONE
No full textQuesto testo ha considerato la complessità della valutazione di costi e benefici dell’immigrazione. Si è detto che lo stesso concetto di immigra- zione nella presente situazione di globalizzazione sta perdendo di senso o assumendo significati diversi. È comunque possibile valutare aspetti par- ziali dell’impatto del fenomeno migratorio sulla nostra economia. I punti più controversi e cruciali nello stabilire delle appropriate politiche su que- sto tema sono l’impatto sulla produttività del lavoro e sul livello salariale. Possiamo sostenere che l’immigrazione non sia la causa della perdita di produttività del nostro sistema produttivo né sia la responsabile della dimi- nuzione del livello salariale degli italiani. Semmai ha agito come concausa nel contesto delle riforme del mercato del lavoro e delle politiche di svalu- tazione interna
Talenti e competenze nell’Europa del futuro. I dati del XIII rapporto annuale sull’economia dell’immigrazione
Full text linkThe historical period we are experiencing is considered a crucial transition due to its relevant de-
mographic, economic, social, health and environmental changes. The COVID-19 pandemic re-
shaped how also in the perception of such phenomena, allowing a change in paradigm that trans-
lates in unprecedented policies and investments. Particularly, at the European level, the core of such
a paradigm is shaped by the green and digital transitions. According to the European Commission,
such changes plead for new skills that will inevitably affect the labour market and the socio-eco-
nomic dynamics. For that reason, 2023 was declared the «European Year of Skills», with actions
and investments dedicated to the empowerment and enhancing of individuals’ skills and to favour
the link between expertise and labour opportunities. In this regard, the situation in Italy appears
particularly delicate, with high rates of female and youth unemployment and a strong turn-out of
young people that do not study nor work (NEET). Moreover, even the presence of immigrants in
Italy, that has steadily grown and represents more than the 8% of the population, suffers from the
difficulties of the labour market. Italy mainly attracts unskilled labour, that is found in seasonal and
manual works. Even skilled workers are often placed in low-level jobs («overqualification»), creat-
ing a social immobility that limits integrational chances and determine talent waste. Nonetheless,
immigrants enduringly represent a tenth of Italian employment and support production for the
9% of the GDP, with even greater peaks in the agricultural and building sectors. Italy and Europe
are therefore bound to face many challenges if they wish to reach the Sustainable Development
Goals (2030 Agenda) and those of the EU Next Generation plan (implemented in Italy through
the PNRR). Undoubtedly, the enhancement of youth, women and immigrants’ talents represent one of the key points of such journey. It is no coincidence that the Italian government has foreseen
the entry of 452,000 non-EU workers for the three-year period 2023-2025, effectively reopening a
channel that had remained virtually unused for about a decade. Furthermore, immigrant entrepre-
neurship is continuously growing, confirming the propensity of immigrant workers to start their
own business. Such phenomena, which, on the one hand, represents the continuation of a path of
emancipation and stabilisation, on the other hand, it shows challenges, especially regarding its co-
existence (and the creation of synergies) with the native productive structure. The 2023 Report on
the economics of immigration is the opportunity to trace a snapshot of Italy from the point of view
of talent promotion, by highlighting also migration dynamics and to how these can commit to the
economic recovery
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
